Description:

This register is used to enable the interruption from a system related interrupt source

to the host. Writing ‘1’ in this register enables the corresponding interrupt event to

generate interrupt signal at the INT pin. Note that even if the interrupt is not enabled,

an interrupt event is still reflected in the interrupt status register.
